Pyramidal neurons (pyramidal cells) are a type of neuron found in areas of the brain including cerebral cortex‚ the hippocampus‚ and in theamygdala. Pyramidal neurons are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract. Pyramidal neurons were first discovered and studied by Santiago Ramón y

Cassandra Burkepile April 27‚ 2014 General Psychology The Cerebellum The Cerebellum of the brain is located at the end of the brainstem. The tissue is folded into itself several times and each layer helps with the organization on the mind. Over time‚ scientists discovered that this bean shaped matter has a lot to do with coordinating voluntary movement. However‚ new discoveries show that damage to the cerebellum affects how people are able to identify sensory information and

The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

The effector neurons of the myenteric plexus may be excitatory or inhibitory according to the substances released in contact with smooth muscle cells. Excitatory neurons release acetylcholine‚ substance
